Firefox Support Forum

I have an older PC but it was working fine with Netflix and Prime Video until this latest update (v89.0). It seems that when I try to go to Netflix or Amazon Prime Video the browser crashes almost instantly, and usually shuts my whole computer off. It doesn't go to a blue screen, the computer just decides it's time to reboot. Now again, I'm using an older machine (and I can't afford a new one), but this was never a problem until this latest version of Firefox.

I am also not a fan of the aesthetics in this version and I'm wondering if I can revert back to an older version where the crashing was less frequent. Any help would be appreciated.

Upon the subject action, Windows 10 takes a system/memory dump, sends it to Microsoft, and automatically restarts. Firefox appears to be initializing for about 3 seconds (after clicking its shortcut) and then the crash occurs. The display of the initial Firefox landing page is not obtained.

The blue screen of death (BSOD) has this message: KMODE EXCEPTION NOT HANDLED

Also, the networking software (NETGEAR) is rendered inoperable and must be re-installed upon Windows restart. Otherwise, my system is stable. Maintenance is regularly applied as it becomes available.

Firefox was a delight to use. But now not so much, as it's unavailable as described above.

If anyone has a fix, or a suggestion for obtaining one, it would be gratefully appreciated. Thanks!

Possible coincidence, but suspicious! Re: Firefox 81 [from the 100s of ‘hits’ I see here now, likely a Ffx bug]

Written from wife’s PC since mine is now crippled. I upgraded to Firefox 81 on my own PC, reluctantly, for “security” fixes, NOT for the big new feature I don’t want. Last night I downloaded v. 81 then closed Ffx and shut down the PC late at night. (It runs Win 7 with all the relevant updates I know.)

Today after booting, it showed my normal desktop. But my email app (located on D: drive) would not open either from shortcut or from Programs menu. Same for all the other apps I tried to open, even on C: drive, including ms_Office. Almost any app would bring up “server execution failed.”

Now, after a few hours on “Sleep” then reopening: --Nothing but a black screen (w/cursor) for 5-10 minutes anyway; --Later a plain blue screen, in small type on lower right: “Windows 7 build [no.] / “This copy … not genuine” –although it came installed, straight from Dell!

I hope mozilla can help cure this in its paralyzed state – and get me back to v. 80.0.1 that worked!
